The car is on shipping blocks and "Slave Wheels" Specially designed and aerodynamically efficient wheels will be added later , the car was doing a segment for an upcoming Web TV feature like the Gina and the X6 Concepts before it.

Internally it is known as Vision Z or Z6.

looking at the angle similar to this picture and you can see a very prominent swage line as well as similar shapes to the headlights cut-outs.

here is my 5 minute attempt at what the rest of this thing looks like...its hard to tell with the garbage bag on it...but judging from where the door cut is, it looks to be a 4-door. i put different (terribly drawn) wheels on it too

Actually it does. It now forms the shape of the frameless glass rear door window.
Other manufacturers have effectively taken the BMW design element and applied it to their own products it is right that BMW effectively keep the look but progress it that it stands far from the immitators.

alot of times the fiberglass and foam models have adjustable suspension, so that the ride height can be fine tuned for asthetic reasons. they might just have it jacked all the way up to get it on the truck safely

OMG WTF IS THAT AWESOMENESS!!!!! I would think they would cover up a 1 off with i dunno maybe some kinda canvas or an actual CAR COVER, it would have to be a generic one but still. They basically covered it with plastic bags and masking tape and called it a day.

That cover's not generic...It's a custom bimmerpost light weight car cover. Didnt you see all the graphics on it?
